Rock legend Jimmy Page has been giving evidence in an alleged bootleg music case at Glasgow Sheriff Court.

Robert Langley, from Buckinghamshire, has denied 12 charges of trying to sell bootleg material in the city in 2005.
Former Led Zeppelin lead guitarist Page, 63, was shown hundreds of CDs and DVDs containing the band's material.
The star told the ongoing court case that the discs had never been authorised for manufacture, distribution or sale.
Mr Langley has been accused of trying to sell the material at the Scottish Exhibition and Conference Centre (SECC) in Glasgow.
There was little fuss as grey-haired Page arrived to give evidence in court number five.
He stood in line to go through the court security scanner at the entrance before proceeding into the witness room, accompanied by two police officers.
Page was called to give evidence as some of the material seized included previously unreleased performances by his band, such as concerts at Knebworth and in Japan.
Many fans, lawyers, police officers and even two sheriffs took their seats in the courtroom to catch a glimpse of the star.
Page told the court that a massive "personal collection" of unreleased Led Zeppelin performances had been stolen from his Berkshire home in the early 1980s.
He was asked by officials from the British Phonographic Industry to visit Glasgow following a raid at the city's SECC in May 2005.
It concerned a seizure of CDs and DVDs from Mr Langley, a trader who had been selling goods at the centre.
Fiscal Judith Hutchinson showed Page some of the items found, which included a £220 CD boxset of a Led Zeppelin tour in Japan and a £40 set of a warm-up session in Denmark.
Murray Macara, defending, said the accused claimed to have met Page in Miami in 1993 but the star said he did not know him.
The trial then heard about a charity event in London where it was claimed that Page got up on stage to jam with former Wimbledon tennis champion Pat Cash.
Mr Macara claimed Page's daughter had taped this and passed it on to a photographer friend, in effect "bootlegging", all with the guitarist's permission.
The lawyer said this perhaps showed Page's attitude to piracy was not as "strict" as it seemed.
But, the rock star said: "The legitimate part is where fans trade music, but once you start packaging it up and you do not know what you are getting, you are breaking the rules legally and morally.
"There are some of these recordings where it is just a whirring and you cannot hear the music.
"If you have something like this that appears legitimate then it is just not right."
Page then told how he went into a major record store in New York and caught them selling pirate Led Zeppelin music.
He said: "I went to check what they had for the band and Jimmy Page and found a gig from Earl's Court in London
"I do not know where it surfaced from, but I contacted my New York lawyers to say the shop was selling something as if it was official, but clearly it was not."
Page later left court with bodyguards after signing autographs for a queue of fans.
Mr Langley denies 12 copyright and trademark breaches.
The trial, before Sheriff Sam Cathcart, continues.
